I don't think my any firearms training made me more aware of my surroundings, but when I started carrying a gun years ago what I was looking for probably changed a little. Honestly, as far as a motor vehicle goes, riding a motorcycle did much more for being my awareness while driving anything then carrying a gun or training did. Having a police car with no lights or siren run a stop sign and miss my rear wheel by a couple of inches and having a dump truck slide past me sideways while I was sitting at a red light on my bike sort of woke me up to the risks that surround us every day.
